Using Bio-Replicated Forming Technologies to Fabricate Shark-Skin Surface
Brazilian Archives of Biology and Technology, 2018 Shark-skin surfaces show the non-smoothness characteristics due to the presence of riblet structures. In this work, biomimetic shark-skins were prepared by means of different bio-replicated forming techniques.

Acta Psychiatrica Scandinavica, Volume 153, Issue 6, Page 610-626, June 2026.ABSTRACT Introduction Suicide risk is markedly elevated following presentation after self‐harm, yet the evidence base for interventions initiated in the immediate post‐presentation period has not been synthesized with specific attention to this high‐risk window. Clarifying which early interventions may reduce adverse outcomes is essential for informing

Influence of Wall Deformation Structure on the Liquid Film Flow Behavior Under Turbulent Conditions
Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.ABSTRACT To explore the influence of typical wall deformation structure in the scrubbing‐cooling tube on the liquid film, this paper studied the liquid film flow behavior on the riblet walls with representative riblet radii and compared them with the flat wall. Under different liquid film Reynolds numbers (Rel = 8.3 × 103 ~ 3.14 × 104), the liquid film

Effect of Different Flow Directions on Drag over Riblet
Journal of Applied Fluid Mechanics, 2020 Variation in flow direction requires extensive consideration in the practical application of riblet surfaces. However, studies scarcely examine the impact of flow angle α for riblet, which is usually adopted to reduce flow drag.

Controllable deformation based self‐adaptive drag reduction for complex surface
Biosurface and Biotribology, 2023 Reduction of energy consumption and improvement of cruising speed are greatly necessary for underwater vehicles. Previously, regular riblets have been machined and the drag reduction has been verified; however, the riblet parameters are not adjusted like
